Emerging Asian equities diverged on Monday, as a 5% slide in South Korean shares underscored a deepening unwind in the AI trade, while an escalating war in the Gulf drove oil prices higher and revived inflation concerns across the region.
Shares in Seoul .KS11 fell as much as 5.1% as trading resumed after a market holiday on Friday. The benchmark KOSPI gauge has slumped more than 22% for the month so far, confirming a bear market.
Taiwan's tech-heavy index .TWII rose as much as 1% before paring gains, while the MSCI EM Asia equities index .MIMS00000PUS edged 0.5% lower.
The South Korean and Taiwanese benchmark gauges together account for about 60% of the MSCI equities index.
"Investors now are reassessing the sustainability of AI capex demand in the longer term, and Korea, which produces AI memory chips for data centres, are more sensitive to changes in market sentiment," said Kelvin Lam, senior China economist at Pantheon Macroeconomics, while noting that Taiwan's ecosystem is lesser exposed than South Korea.
Citi analysts cut Korea to "neutral" in their EM country allocation, from "overweight" since July 2025, citing volatile trading conditions even as the market continues to rank strongly in their fundamentals-based models.
Markets took a further hit on Friday after Chinese AI firm Moonshot unveiled Kimi K3, an open-weight model it said nears Anthropic's frontier Fable system, raising the stakes for this week's earnings from Alphabet GOOGL.O, Intel INTC.O and Tesla TSLA.O.
"This inevitably revived intense, DeepSeek-esque worries about a race to the bottom on model compute undercutting staggering investments by hyperscalers," said Vishnu Varathan, head of economics and strategy at Mizuho Bank.
